摘要： PROBLEM TO BE SOLVED: To improve abnormality determining precision of output of a throttle opening sensor.
SOLUTION: In a system for comparing output (detected throttle opening) of the throttle opening sensor with a noise determining value N to determine the presence or absence of noise, the noise determining value N is set to a value raised by a predetermined value α for a base value Nbase when amount of change ΔTAtg per computation cycle of target throttle opening is larger than a threshold value H to prevent change of output of the throttle opening sensor in a transition period from being erroneously determined. On the other hand, when amount of change ΔTAtg of target throttle opening is below the threshold value H, the noise determining value N is returned to the base value Nbase to increase noise detection sensitivity.

摘要： PROBLEM TO BE SOLVED: To provide a control device of a variable valve train, which suitably determines the state where a detected valve characteristic shifts from an actual value. SOLUTION: When engine rotation speed NE is equal to or higher than a determined value A (S300: YES) and voltage reduction occurs in the control device of a motor driving the variable valve train (S310: YES), an instantaneous counter C is updated (S320). When a target valve characteristic has been varied just before the occurrence of voltage reduction (S330: YES), a second shift determination value Zb set at a value smaller than a first shift determination value Za is set as a shift determination value Z (S350). When the instantaneous counter C exceeds the shift determination value Z (S360: YES), a shift determination flag FZ is set to be "ON" (S370) and the detected valve characteristic is determined to be in the state of shifting from the actual value.

摘要： PROBLEM TO BE SOLVED: To provide a throttle control device increasing possibility of escape from seizure of a throttle valve due to icing or foreign matter.
SOLUTION: This throttle control device tentatively relaxes limitation of the maximum drive current of a motor drive circuit 4 by a maximum current limiting circuit 48 when any one or more of intake air temperature, temperature of a switching element of a driver 40, water temperature and lubricating oil temperature or the like is low. A countermeasure for overheat of the switching element of the driver 40 is performed because a condition at a time of low temperature is relaxed as compared with a condition at a time of high temperatures. The relaxation is performed by limiting time to prevent overheat of the switching element. Consequently, possibility to releasing seizure of the throttle valve 10 can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular control system that can increase reliability further even when safe running of a vehicle for repair is executed, by executing more suitable fail-safe processing after an anomaly determination about an electronic control unit. SOLUTION: The system is mounted on a vehicle having a control microcomputer 31 for electronically controlling operating modes of fuel injection valves and spark plugs in dependence on an operating state of an on-vehicle engine, and a monitoring microcomputer 32 for determining an anomaly occurring in the control microcomputer 31.
